Description

Technical Field

[0001] The utility model relates to the technical field of winding tooling, in particular to a winding tooling for an air-core reactor coil used in rail transportation. Background Art

[0002] Reactors are mainly used in power systems to limit short-circuit current, compensate for reactive power, and shift phases. They are inductive high-voltage electrical appliances. Reactors are generally made of wires wound into a solenoid form, called air-core reactors. When winding, a winding machine is usually used in conjunction with winding tooling to wind the wire into a reactor coil.

[0003] When the hollow reactor coil winding tool is in use, it is necessary to ensure the hollow state of the central area of ​​the reactor coil. Therefore, some supporting components are often set on the winding tool so that the supporting components can form internal support for the coil during the winding process. Although the supporting components set on most existing hollow reactor coil winding tooling can play a good supporting role when in use, the disassembly and assembly work is relatively inconvenient when the coil is disassembled after winding is completed, which greatly reduces the production efficiency of the device. Utility Model Content

[0004] The purpose of the utility model is to provide a hollow reactor coil winding tool for rail transit, so as to solve the technical problem that most existing hollow reactor coil winding tools are inconvenient to disassemble the coil after winding.

[0026] The utility model comprises two groups of No. 1 side panels 1, and the interior of the two groups of No. 1 side panels 1 is provided with a No. 2 side panel 2, and the opposite sides of the No. 2 side panel 2 are provided with a limited circular groove 3, and the side walls of the limited circular groove 3 are provided with a positioning groove 4, and the positioning groove 4 is rectangular. An expansion sleeve 5 is provided between the No. 2 side panels 2, and an outward-expanding inner cavity 6 is provided inside the expansion sleeve 5. The expansion sleeve 5 is assembled by three groups of equally divided expansion sleeve parts, and the outward-expanding inner cavity 6 is in the shape of a flat-top cone. A matching supporting core shaft 7 is provided inside the outward-expanding inner cavity 6, and a fitting block 8 matching the positioning groove 4 is provided at one end of the supporting core shaft 7. Several groups of spaced center rods 9 are provided on the inner side of the No. 2 side panel 2 around the outer edge of the limited circular groove 3, and several groups of spaced-apart rack rods 10 are inserted into the inner side of the No. 1 side panel 1, and the rack rods 10 are located The outer side of the No. 2 side plate 2 and the outer side of the frame rod 10 are provided with an insulating member 11 for separating the coils 12. Several groups of fixing grooves 14 are provided on the No. 1 side plate 1 and the No. 2 side plate 2. Both the No. 1 side plate 1 and the No. 2 side plate 2 are machined with carbon steel as the main material. The thickness of the No. 1 side plate 1 is 10 mm, and the thickness of the No. 2 side plate 2 is 60 mm. The No. 1 side plate 1 is mainly used to install and fix the No. 2 side plate 2 and the frame rod 10. The limiting circular groove 3 provided on the No. 2 side plate 2 is used to install the expansion sleeve 5 and to form a limiting fixation for the expansion sleeve 5. A group of positioning grooves 4 provided on the No. 2 side plate 2 is used to install the fitting block 8 at one end of the support core shaft 7. The fixing grooves 14 provided on the other group of the No. 2 side plate 2 are used to fix the other end of the support core shaft 7. Thus, the expansion core shaft 7 is supported by the support core shaft 7. The sleeve 5 forms a support, so that the expansion sleeve 5 expands, and the expansion sleeve 5 cooperates with the center rod 9 to form a support structure in the central area of ​​the device, thereby ensuring that the center of the coil is a hollow structure during winding. The expansion sleeve 5 is machined from aluminum alloy to ensure the strength of the expansion sleeve 5, which can play a role in stable support. The rack rod 10 is used to install the insulating member 11.

When winding, the insulating parts 11 are uniformly moved to the side away from the winding end. After completing a group of windings, the staff can move a group of insulating parts 11 over, and repeat this operation to insert the insulating parts 11 into the coil, thereby realizing the separation between the coil groups and ensuring good heat dissipation of the coil when in use. After completing the winding, the staff can directly disassemble the No. 1 side plate 1 and the No. 2 side plate 2, and then pull out the supporting core shaft 7. Since the expansion sleeve 5 is assembled by three groups of equally divided expansion sleeve parts, it can be broken down into parts and disassembled one by one during disassembly.This avoids the inconvenience of disassembling the large expansion sleeve 5.
